Stainless Steel 3-Pos.4-Way Rotary Valve: This valve is a shear-type rotary valve. Foreign substances in the oil are less likely to enter the sealing surface, thus preventing leakage. The wave spring generates pre-pressure on the sliding sleeve, ensuring sealing at low pressure; the pressure oil pushes the sliding sleeve to exert a sealing aid effect, ensuring sealing at high pressure.
SAE flanged check valve: Based on the traditional one-way valve structure principle, it adopts SAE flange connection, ensuring more stable sealing under high-pressure and shock-resistant working conditions.

The wave spring generates pre-pressure on the sliding sleeve, ensuring sealing at low pressure; the pressure oil pushes the sliding sleeve to exert a sealing aid effect, ensuring sealing at high pressure.
Hydraulic check valve: The hydraulic control check valve is equipped with a pilot control oil port. When the control port has no pressure, the pressure at the inlet port will be cut off; when the pilot control port is connected to pressurized oil, the push rod pushes the check valve core open, enabling the hydraulic flow from the inlet port to the output port.
1/4"Hydraulic-Controlled Pneumatic 2-Pos.5-Way Valve: It uses hydraulic signals to control mechanical switching, and then converts the gas path for switching, thereby achieving bidirectional control of pneumatic components.
1/4"Pilot-operated Hydro-Pneumatic Pressure Switch: It can be used as the main control switch for pneumatic-hydraulic components， such as pneumatic-hydraulic pumps and other hydraulic elements， to achieve functions like controlling the oil pressure of the hydraulic system. When the system oil pressure reaches the set upper limit, the Hydro-Pneumatic Pressure Switch cuts off； when the system oil pressure reaches the set lower limit, the Hydro-Pneumatic Pressure Switch connects to the air source.
Manual Regulator: This valve is of the shear type and will not be blocked by oil contamination, thereby not affecting its performance; the piston and sliding sleeve are not prone to wear and have a long service life; the wave spring is pre-sealed and oil pressure assists in sealing, with a reasonable structure.
Pneumatic pump: Utilizing a large liquid-to-air ratio and direct linkage method, it exhibits excellent performance in starting under heavy loads, especially when dealing with extremely high hydraulic loads, it can still start smoothly.
The Hydraulic Drive Regulator achieves stable output regulation of the outlet pressure by adjusting the hydraulic pressure at the pilot port, thus forming a negative feedback regulation involving pressure, displacement, and flow rate.
